Kacchi Dargah-Bidupur Bridge

Kacchi Dargah-Bidupur Bridge is a six-lane structure crossing the Ganges River in the state of Bihar, designed to connect the northern and southern banks. The roadway includes pedestrian walkways along both edges, allowing people to cross on foot alongside vehicles.

Planning for this structure began in August 2015 when the Chief Minister of Bihar laid the foundation stone, addressing a long-standing need for direct access across the Ganges. Construction work started in July 2017, bringing the state closer to connecting its northern and southern territories by road.

The bridge connects communities on both sides of the Ganges River, taking its name from the local shrine area of Kacchi Dargah.

The structure is expected to open in 2024, providing a direct connection between National Highway NH-31 and NH-322 once it enters service. Travel time between the northern and southern parts of Bihar will shorten considerably, removing the need for a wide detour.

This structure is the longest river crossing in India and requires a total of 87 foundations, anchored partly in water and partly in the surrounding floodplain. The design spreads 67 foundations across the Ganges itself and 20 more in the adjacent Diyara zone, which floods regularly.
